Abstract
To provide a structure for achieving high transmittance in a lateral-electric-field mode liquid crystal display device through stably controlling the domains in the terminal parts of comb-shaped electrodes where the liquid crystal molecules rotate in the reverse direction. In the lateral-electric-field mode liquid crystal display device in which common electrodes and pixel electrodes are formed on a same layer, a protrusion part is provided in a direction in an obtuse angle with the comb-shaped electrode and substantially in parallel to a scan line in the terminal part of the comb-shaped electrode of the pixel electrode or the common electrode, a floating electrode is extended in the extending direction of the comb-shaped electrode to overlap with the comb-shaped electrode in the terminal part, and a liquid crystal reverse rotation locked structure is formed with the protrusion part of the comb-shaped electrode and the floating electrode.
